IOS Cryptic

[FlickMay]

Can any of you clever people out ther help with 2 clues in today's IOS cryptic, please.

7d) Sin over? Clue to that is in the Bible (7,7)

-E-I-E- V-R-G-- (and I think* first letter, first word is R)

[7a) Crude offensive to the west (3) = RAW*]

25a) Saw a donkey's tail lying in grass (6)

S-Y---

The last letter of the down light is the 5th if this.

Any suggestions gratefully received

Cheers!

25a is saying

to grass = to sing
donkey's tail = Y
so put A Y in SING and you get saying (a saw)

Thanks gen2 - never knew a saw was a saying. Makes 7d even worse ...
